Every Marvin Window and Door is made to order, one at a time. An unparalleled value in the market, Marvin offers craftsman-quality construction, energy-efficient technology and the industry’s most extensive selection of shapes, styles, sizes and options.

Integrity's windows and doors are made with Ultrex® Fiberglass, an innovative material created 20 years ago. For two decades now, Ultrex has outlasted and outperformed the competition on virtually every measurable scale.

Infinity Ultrex fiberglass replacement windows and patio doors are designed to replicate the look of traditional wood windows while providing modern features and low-maintenance, yet long-lasting performance.

When you partner with Marvin on your next project—whether that be a remodel, replacement, new construction, or even the creation of sustainable building—you can be sure you will be getting the guidance and expertise necessary to make any design complete. Tell us a few things about your project, and Marvin will work with local dealers to bring your ideas to life.

Midway through the entry period, we are very impressed by the quality of submissions we have received for the 2014 Red Diamond Achiever Award program. Each year, the program recognizes outstanding design, innovation, sustainability and quality in projects by the nation’s premier builders, remodelers and architects using Integrity products.

One aspect that keeps this program fun — but also challenging for our judging panel! — is the sheer diversity in projects submitted. From classic to modern, rural to urban, residential to commercial, we tend to see a little of everything. We are continually amazed by the creativity, vision and craftsmanship in the building industry.

That in mind, we thought we would take a trip down memory lane and show you some of our favorite photos from past winners. We also want to remind you the deadline to enter or nominate a project is June 26, 2014. You can read the full entry details here. And keep in mind Integrity is giving a free $50 Cabela’s® gift card for each entry as a thank-you to those who take the time to submit.
